LH 3000 with SCO UNIX 5.0.5

I used canned air to clean out the system yesterday and now the fans are all
stuck on high speed.

This server has been fine for years and now I am wondering what is going on.

I was as carefull not to touch anything while cleaning, other than unplug
the power cord and take off the sides.

The server boots up fine and there are no problems with the OS.

The fans will just not idle down like they use to upon powerup.

I never entered the BIOS or changed anything. I tried to stop that dang
Murphey from bitting me
in the butt.
